This is good. I used an unrefined extra virgin olive oil, homemade chicken stock as that is what I had on hand (well flavoured), puy brown dry lentils, a good quality canned (Primo brand), whole plum tomatoes which I chopped myself as I find they taste better than buying the chopped ones. I used dried oregano, no optional mint, sea salt and the rest. I don't think I will make this soup again.
